If the price was really cheap, maybe see if you can make a little on it, I really think it sounds like you bought way too much sled for your needs. Like I said, I had a f3 too, and it was just not a great ice fishing sled, its too heavy, has a "need for speed", and the f3 is known for engine troubles. But I don't share your sentiments about the electric start and reverse either, they just add weight in my opinion.
Just keep your eyes open for a better sled, you might find you don't like this one too much.
